Central Heating Power Flush

Loss of water pressure?

A central heating power flush should cure it

Over time, deposits build up in central heating systems which reduce the free flow of water and have an adverse effect on efficiency by as much as 65%.
As the sludge of iron oxide deposit accumulates in the system it results in poor circulation, fuel wastage, system noise and premature failure of some of the components. A central heating power flush can remove this sludge and improve performance exponentially.

An easy test you can carry out yourself is to check the radiator furthest from your boiler. With the heating running, put your hand on the top centre of the radiator for just a few seconds. Then place your hand on the bottom centre. If it’s colder at the bottom of the radiator than the top then it is probably blocked by a build-up of sludge and you would benefit from having your central heating system power flush.

Other signs that your system may need a power flush

If your central heating system is serviced regularly, it should only need power flushing every five years. A power flush is highly recommended before a new boiler is installed. This is something that we do as standard when carrying out boiler replacements.

Andy of the following could also be a sign that your system needs power flushing:

  • Little or no hot water – Blocked pipework and/or heat exchanger due to excess build up could also be the reason for your heating system producing little or no hot water.
  • Cold spots on radiators – If your radiators are cold at the bottom but hot at the top: Your heating system could have a sludge problem. Cold spots are caused by the build-up on iron oxide sludge, this collects at the bottom as its heavier than water, which restricts to the flow of hot water.
  • Dirty water when bleeding radiators – Bleeding your radiators can help improve heat circulation and convection. However, if the water is discoloured when bleeding your radiators, this could be a sign your heating system needs a power flush.
  • Pump or valve seizure and/or failure – Black oxide sludge increases wear and tear on the shaft and bearings, which is the most common cause of pumps seizing or failing completely. A stuck valve could result in a very inefficient radiator.

How This Can Be Fixed?

Have your central heating power flushed by Lenzie Plumbing from just £400 and you will notice the improvements:

  • Improved efficiency of your central heating system
  • Eliminate boiler noise
  • Restore heat output
  • Lower fuel bills

We will also fit a Fernox TF1 magnetic in-line filter free of charge to remove magnetic and non-magnetic contaminanets.

And all work carried out to a professional standard for just £400
